Like calling someone new and saying “Looking forward to hearing from you” without leaving your number, or (my personal favorite) “It’s really important you read over the attached documents and get back to me ASAP,” then forgetting to attach it to the email.

IFF “1” is a prime, then I’d say 150 folks. If not, 140. Good times!

Here’s an easy way to remember that 1 is not a prime: A prime is a positive integer with exactly two divisors. The number 1, of course, has only one divisor (itself), and all composite numbers have more than two divisors. Only primes have exactly two.
